My tug 'Denton' , an ex Smit Nederland, has the stock Becker rudders.
My problem is this: If I use a little too much helm, the linkage pin circled in the photo comes out of its swivel mount and I then have no control over the rudders at all. They just waggle and I have to drive the tug back to shore as best I can.
The previous owner tried to stop this by installing a mechanical linkage from the rudder control arm, connected to a rod that slid back and forth, with a couple of stops on it to restrict its movement, shown in the second photo. This didn't work well and it would either jam or slip.
So, in the menu of my transmitter (Futaba T6EXP) I set a maximum throw for the rudders, but I still occasionally lose control with the pins coming out.
Anyone else had this issue? Any solutions?
